Mine plant dust removal purifier for environmental protection equipment

Abstract

A disclosed mine plant dust removal purifier for environmental protection equipment structurally comprises a dust removal main machine, a draught fan, a dust discharging opening and supporting legs, the draught fan is fixedly installed at the upper right end of the dust removal main machine in an embedded mode and communicates with the dust removal main machine, waste gas at the lower end enters an air inlet to blow a rotating piece to rotate, and a protective shell rotates stably. An electric heating wire in a connecting rod rotates to heat, and hot air is rotatably discharged through the air holes, so that the whole dust at the upper end in the box body is more uniformly insulated, and the dust in the waste gas is prevented from staying in a filter bag due to too low dust temperature and too large moisture in the waste gas. During filtering, waste gas blows a sliding block to slide in a fixed block, so that the filter bag shakes, meanwhile, the waste gas is discharged into a fixed ring through a gas inlet hole, the sliding block is blown to annularly rotate on a guide rod, a pressing block rotates and extrudes the outer side of the filter bag, and dust condensed and adhered to the inner surface of the filter bag is prevented from falling off.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, and more specifically, relates to a mine dust collector for environmental protection equipment. Background technique [0002] In the process of ore crushing and screening, material transfer, ore bin feeding and discharging, dust is emitted from places where excess pressure is generated. It is necessary to use a bag filter to effectively ventilate and remove dust to avoid dust in the mine. Free diffusion pollutes the working environment and the atmosphere. However, due to the low temperature of the mining plant in the northern winter, the dust generated in the mining plant itself has a low temperature and high humidity. The bag filter is processing When there is dust gas with high relative humidity, the inner filter bag is prone to condensation, which will cause the dust to condense and adhere to the filter surface of the dust bag, which will greatly reduce the effective filtering...

Problems solved by technology

[0002] In the process of ore crushing and screening, material transfer, ore bin feeding and discharging, dust is emitted from places where excess pressure is generated. It is necessary to use a bag filter to effectively ventilate and remove dust to avoid dust in the mine. Free diffusion pollutes the working environment and the atmosphere. However, due to the low temperature of the mining plant in the northern winter, the dust generated in the mining plant itself has a low temperature and high humidity. The bag filter is processing When there is dust gas with high relative humidity, the inner filter bag is prone to condensation, which will cause the dust to condense and adhere to the filter surface of the dust bag, which will greatly reduce the effective filtering area of ​​the filter material, and the air permeability of the filter material will drop sharply. The running resistance of the type dust collector becomes very high, resulting in an increase in the load of the induced draft fan and an increase in energy consumption. In severe cases, the induced draft fan will be overwhelmed and difficult to operate.
